PostCSS Unset Value

PostCSS Unset Value lets you use the unset keyword, following the CSS Cascading and Inheritance specification.

.color {
	color: unset;
}

.border-color {
	border-color: unset;
}

.margin {
	margin: unset;
}


/* becomes */
.color {
	color: inherit;
}

.border-color {
	border-color: initial;
}

.margin {
	margin: initial;
}

Usage

Add PostCSS Unset Value to your project:

npm install postcss @csstools/postcss-unset-value --save-dev

Use it as a PostCSS plugin:

const postcss = require('postcss');
const postcssUnsetValue = require('@csstools/postcss-unset-value');

postcss([
  postcssUnsetValue(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);

PostCSS Unset Value runs in all Node environments, with special instructions for:

Node	PostCSS CLI	Webpack	Create React App	Gulp	Grunt

Options

preserve

The preserve option determines whether the original source is preserved. By default, it is not preserved.

postcssUnsetValue({ preserve: true })
